There are only three seasons in Kerala, though some divide the rainy season into two. Rainy season usually prevails in Kerala for about 5 or 6 months with dry spells intermittently. Monsoon season starts from June and ends by November. December and January are cold months, as the sun then is in the southern hemisphere. Coolest nights are in January, or sometimes in December.

Warm weather conditions prevail for a brief period after the winter conditions, when flowers blossom and cover the countryside with multi-colors.

Dry season, or hot summer arrives in April and the atmosphere becomes hot and moist. Rivers go dry in hot season and people face drinking water scarcity problem. Fortunately, usually there are rains during the dry season, which make the Kerala terrain a more salubrious land compared to most other Indian states.

Tourist Season
Earlier the rainy season was considered as off-season for tourism. But now monsoon season is also promoted, as there are many tourists who are attracted by rains.
